Malware removal is only the first step in fighting an infection.
Your job isn’t finished until you’ve determined what the malware is, how it breached your defenses, and how to prevent similar infections in the future.
Your browser history tells the malware tale
My past malware-related columns focused on removing an infection. This is usually the immediate goal when working to fix your home PC. But it’s not the only goal.
For example: In a corporate setting, a good IT department will not only remove an infection but also do a forensic analysis to determine how the malware got in, what damage it did, and how to prevent recurrences.
There’s no reason why you can’t do the same on your own PC.
In my experience, when malware infiltrates a PC, it usually comes in through the machine’s browser. Fortunately, browsers maintain extensive logs of your Web activity, and some of these can be the key to a successful forensic investigation of just how the malware got in.
